HORSESHOE MACHINERY.

Specification of Letters Patent No. 9,390, dated November 9, 1852.

T 0 all whom it may concern:

Be it known that I, SOLOMON SI-IETTER, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Machine for Making Horseshoes, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and of the usual manner of making, modifying, and using the same.

My improvement consists in the arrangement of certain levers, revolving dies and cams, in the manner hereafter described, for turning and forming a horse shoe.

Many attempts have been made heretofore to form horseshoes by machinery, but they have never, but in one instance been brought into practical use; and even in that case they are not formed as they are by hand, and are comparatively of less value than the hand made shoes. I have at last succeeded in making a shoe equal to those made by hand by my combination; the construction of which is as follows.

There are two uprights, A, A, which are similar to the cheeks of a rolling mill; and in these are the brass bearings, in which are two parallel rollers, B, B as in a rolling mill, except the distance at which the rollers are placed apart. Upon these rollers are placed segmental dies, or blocks, C D, that revolve with the rollers, and come in contact at each revolution these dies are removable and can be changed to different sizes. The block D, on the upper roller is concentric on its face, with the roller to which it is affixed, its outline being in the shape of the curve of the shoe to be formed; the lower die or block O has upon its face what I de nominate a core (CZ) just the shape I desire the internal rim of the shoe. The rabbet (c) surrounding the core ((Z,) is made of unequal depth, being shallow at the toe, and deepest at the heel, as the shoe should be. On either side of the dies are rollers J these rollers are on the short arms of two lovers I, whose fulcrums are at (e) in the stationary part of the frame K, and can be set up or off, and accurately adjusted to the dies above named at will; beyond this fulcrum point K, there is a cam shaft geared to and revolving with the above named rollers, which are also gearedtogether by spur gear (1),) after the manner of rolling mills; there is a projection on the cam shaft, where are fitted two face cams H H, against which the long arms of the levers bear, and by which they are worked, the proportion between the long and short arms may be determined by the judgment of the constructor. This arrangement forms the equivalent of four rollers running together with the two side rollers vibrating, which is not found in other machines where four rollers run together, the pairs being at right angles, a very important result being obtained thereby, which the adjustable fulcrum perfects. The face cams are adjustable, and are attached to the shaft by the set screws so that they are readily shifted or changed at will.

It will be seen that by my construction. and arrangement of parts, I am enabled to accurately adjust them, and to produce a sufficient amount of pressure at a minimum amount of power expended; and by this means I form as perfect a horseshoe in my machine as is formed by hand, and any sized shoe can be formed in the same machine by simply changing the dies.

The die for punching the holes, creases, &c., is shown at L, upon which a punch N is brought down by means of a lever O, whose fulcrum is in the standard M, and actuated by the eccentric cam P.

Having thus fully described my improvement what I claim therein as new and for which I desire to secure Letters Patent is The arrangement of shifting dies and adjustable levers and cams substantially in the manner and for the purpose set forth.
